Description

Technical Field

[0001] This utility model belongs to the field of mechanical tooling technology, specifically relating to a tool for disassembling the liner of a semi-autogenous grinding mill. Background Technology

[0002] Based on the characteristics and process requirements of semi-autogenous mill liners and mineral processing, when the mill liners are due for replacement, due to the wear and tear of the steel balls and liner plates during mill operation, some broken balls enter the liner gaps to varying degrees. As the liner wears and deforms, under the impact of the large balls and ore grinding, the broken balls become increasingly compacted in the liner gaps. At the same time, the liner bolts are deformed due to liner wear, and the bolts are basically encased in the liner. Therefore, the first liner in the first row is extremely difficult to disassemble when the mill liners are due for replacement. Therefore, considering the requirements for liner bolt disassembly and the need for safe, fast, and efficient operation, it is necessary to independently develop a semi-autogenous mill liner disassembly tool. Utility Model Content

[0003] To address the issues described above, and based on practical applications, a user-friendly and easy-to-operate tool for removing semi-autogenous mill liners was designed. This tool solves the problems, making the liner replacement and removal process convenient, maintenance-free, simple to operate, practical, and improving work efficiency.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A tool for disassembling the liner of a semi-autogenous grinding mill includes a jig, positioning bolts, a spatial frame, and a separating hydraulic jack;

[0006] Vertical positioning bolts are connected to the left and right sides of the fixture, and the positioning bolts penetrate the fixture.

[0007] The space frame includes two, located directly below the positioning bolts, with the top of the space frame connected to the positioning bolts; the bottom of the two space frames is used to connect the bolts of the lining plates on both sides of the lining plate to be disassembled, and the bottom of the space frame is provided with nuts, through which the bolts of the lining plate are connected;

[0008] The separating hydraulic jack is placed between the bottom surface of the spatial frame and the liner plate to be disassembled. The top of the separating hydraulic jack abuts against the bottom surface of the spatial frame, and the bottom of the separating hydraulic jack abuts against the bolts of the liner plate to be disassembled. The bolts of the liner plate to be disassembled are removed by using the separating hydraulic jack.

[0009] Two spatial frames are used to connect the bolts on the left and right sides or the front and back sides of the liner to be disassembled.

[0010] The advantages of this utility model are: it makes the replacement and disassembly of the liner plate convenient and maintenance-free, simple to operate and practical, and improves work efficiency. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0015] like Figure 1 and 2 As shown, a tool for disassembling the liner of a semi-autogenous grinding mill includes a jig 1, positioning bolts 2, a spatial frame 3, and a separating hydraulic jack 6.

[0016] Vertical positioning bolts 2 are connected to the left and right sides of the fixture 1, and the positioning bolts 2 penetrate the fixture 1; there are two spatial frames 3, which are located directly below the positioning bolts 2, and the top of the spatial frames 3 is connected to the positioning bolts 2; the bottom of the two spatial frames 3 is used to connect the bolts of the liners on both sides of the liner to be disassembled, and the bottom of the spatial frames 3 is provided with nuts, through which the bolts of the liner are connected.

[0017] The separating hydraulic jack 6 is placed between the bottom surface of the spatial frame 3 and the liner plate to be disassembled. The top of the separating hydraulic jack 6 abuts against the bottom surface of the spatial frame 3, and the bottom of the separating hydraulic jack 6 abuts against the bolts of the liner plate to be disassembled. The bolts of the liner plate to be disassembled are removed by using the separating hydraulic jack 6. The two spatial frames 3 are used to connect the bolts of the liner plates on the left and right sides or front and back sides of the liner plate to be disassembled.

[0018] The method of using this utility model is as follows:

[0019] When replacing liners in a semi-autogenous grinding mill, remove the nuts from the two adjacent liners (either side-by-side or top-bottom) to be removed. Fix the anchor space frame 3 to the cylinder liner bolts 7 and tighten the nuts. Then, insert the jig 1 onto the positioning bolts 2 and tighten the fixing nuts. Next, fix the hydraulic jack base onto the support frame jig 1, with one end pressing against the cylinder bolt to be removed. The separation jack can be moved as needed to apply force to the same liner bolt or bolts of different liners until the liner is pushed out of the cylinder. This semi-autogenous grinding mill liner removal tool has a simple structure, is easy to operate, low in cost, maintenance-free, and reliable in performance. It can be custom-made according to the dimensions of different mill models and specifications and can be widely used.
